BURNING COLLAR.

Application led January 23, 1,928. Serial No.k 248,911.r

This invention relates to improvements in electrical battery workingtools, having for anobject to provide a burning collar device for use inburning or fusing electric storage battery connectors to the pillarposts thereof whereby to insure a positive and efficient mechanical andelectrical connection therebetween, the device being of suchconstruction that with placement or engagement of the same over or aboutthat portion of aconnector engaged over a pillar post, a hot or fusingflame may be directed thereupon from a torch or other device, causingthe even and unifom transmission of heat to the connector and post at atemperature suflicient to effect a fusion of the metals from which theyare formed and hence, with cooling, produce a positive mechanical andelectrical connection after which the burning collar may be v freelyremoved, leaving a finished and nicely appearing job.

The invention also aims to provide a device of the character describedformed of a material whose melting point is above that of the connectorsor posts to be burned thereby, said device, with arrangement about aconnector engaged over a pillar post, serving the dual agency of a shaperetaining mold for the connector and the post during that period when afusing flame is applied to said elements, thereby preventing malshapingof the heat treated portions of the post and the connector and thus,with completion of a burning operation and removal of the deviceansuringa finished and properly appearm0r o afher objects of the'inventionwillbe in part obvious and in part pointed out hereinafter. Y 'c Inorder that the invention and its mode of operation may be readilyunderstood by those skilled in the art to which'it apperta-ins, I havein the accompanying illustrative drawings set out one possibleembodiment of my invention. Y

In these drawings: l

Figure 1 is a side elevation of the improved device applied over abattery terminal and filler during a burning operation, j,

Figure 2 is a top plan view thereof, and

Figure 3 is a vertical transverse section through the same.

vHaving more yparticular referencev to the drawings, in connection withwhich like characters of reference willdesignate corresponding partsthroughout, the improved burning collar consists of a substantially.U-shaped piece of metal whose fusing or melting point is materiallyabove that of the metal from which the connectors and pillar posts inconnection with which it is to be used are formed, constituting a collardesignated for convenience by the numeral l. |The inner and outer sideportions of thefcollar l are arranged in relative parallelism buttaperupwardly as is shown in theFigure 3, whereas the inner side of saidcollar is formed with a cross sectionally semi-circular seat Qcorresponding or approximately corresponding in size and shape to thestandard design and size of battery cell connectors, so that the devicemay be freely downwardly engaged over a battery connector subsequentlyto the engagement of the same over a pillar post; the

free extremities of the collar being thickened as isindicated by thenumeral 3, thus reducmg the 'open side of the semi-circular seat 2 so asyto permit the device to generally conform to the contour or shaping ofa connector engaged thereby.

For convenience in handling or properly adjusting the burning collarwith respect to a connectorand a pillar post engaged thereby` I may andpreferably do provide the same with a handle such as is indicated hereinby the numeral 4, forming said handlefof `a length of suitable material,one end of which is engaged and anchored in a boss or lug 5 castintegral with the outer side and intermediate portion ofy vthe A collarl, the said handle being disposed upwardly with respect to the collarand formed with -a coiled hand grip portion 6 whereby it may be engagedand held by a user without liability of burning-him as'by transmissionof heat from the collar during a burning operation to the handle.

In using .the improved burning collar, a connector such as is shownherein and indicated by the reference character Gis engaged over apillar post P to which the former is to be fusedl and with suchengagement, the burningm'collar is dropped over that portion of theconnector C engaged about or receiving the pillar post P therein. Atthis time,'a hot llame is directed downwardly from f a torch or othersuitable device onto the connector and the adjacent port-ions of thepillar post, hence, melting a portion of the metal of each thereof andcausing a fusion of such molten metals. Following this melting of partsof the connector and the pillar post,

ll() i the flame is removed and the device is permitted to remain aboutthe connector until the same, together with the pillar post have fullycooled whereupon the burning collar may be then drawn upwardly and awayfrom the connector, leaving a finished and, nicely appearing job.

By reason of the shapingv of the burning collar it will be understoodthat the same will serve in the capacity of a shape retaining mold forthe connector engaged about a pillar post to be mechanically andelectrically interconnected and because of this, the malshaping of theconnector during a burning operation will be positively prevented and atthe same time, an efficient mechanical and electrical connection will beproduced between the two battery elements. Also, by reason of thetapered formation of the burning collar l, it will be understood thatthe same will automatically adjust itself to snug engagement over andabout a connector to be burned thereby, such slight variances in size ordesign of the connector being compensated for by the tapering of theinner sides of the collar. Likewise, this upwardly tapering formation ofthe collar l will permit of its free removal from a connectorsubsequently to a burning operation in `that with imparting of an upwardpull to the burning collar from the handle 4, the enlarged lower portionof the collar will readily and freely disengage itself from theconnector and move upwardlythereover.

From the foregoing, it will be understood that I have provided a simpleand high elficient type of battery working tool whereby an effectualmechanical ,and electrical connection may be effected between theconnectors and pillar posts of an electrical storage battery, the deviceserving as a means for positively preventing the mal-shaping of themelted or fused portions of either the connector or the pillar post andin `so doing, permitting the production of a mechanically sufficient andnicely appearing job by comparatively unskilled labor, an item ofmaterial importance to battery manufacturers who, have heretofore beencompelled to rely upon the burning of battery connectors to pillar postsby skilled and highly salaried labor. Furthermore, it will be understoodthat by reason of the inside surface or shaping of the shaping of theburning collar, the device may be successfully used in connection withthe burning of any type of connector now prevalent in 'this particularart, the inside taper of the collar permitting of ample compensation forvariance in cross sectional size or shaping of the connector and at thesame time, permitting the collar to be snugly engaged about saidconnector prior to a burning operation. Herein, it should be noted andunderstood that whereas the outside sha-ping or formation of the collarmay vary within a wide range, the inside shaping or surfacing of thesame will generally correspond to that shown in the accompanyingdrawings whereby the fundamentals of the device may be etl'ectuallyserved, that is, that the collar may be cngaged over battery connectorsof dilferent size or of different shape, according to the products ofdifferent manufacturing con* cerns. Y

Manifestly, the construction shown is capable of considerablemodification and such modifications as are within the scope of myclaims, I consider within the spirit of my invention. i

I claim:
